Plants and Animals

Plant Tissues The primary plant is made up of 4 tissue types: Functional roles meristematic division of new cells for new growth or repair ground tissue bulk tissue; storage, processing, physical support dermal tissue protection and sometimes nutrient absorption vascular tissue movement of fluids/food and physical support

Animal Tissues Epithelial Tissue Epithelial tissue covers external surfaces and internal cavities and organs. Glands are also composed of epithelial tissue. Epithelia forms boundaries. Most substances that move into or out of the body must pass through epithelial tissue. Picture of kidney tubules. Lining the tubules is epithelial cells.

Connective Tissue The cells of connective tissue are separated by non-living material. Connective tissue binds and supports body parts, protects, fills spaces, stores fat (for energy), and transports materials.

Muscle Tissue Muscle tissue contracts in response to stimulation Muscle Tissue Muscle tissue contracts in response to stimulation. It cannot stretch by itself but is strenched by the contraction of other muscles. Muscle tissue is used for locomotion, food movement in gut, and heat production. Skeletal Muscle Smooth Muscle Cardiac Muscle
